Piping joint

Abstract

A piping joint includes: a joint body; a tube inserted into the joint body; a retaining member mounted inside the joint body and located at a distance from an opening of the joint body, the retaining member supporting the tube inserted into the joint body; a guiding member having a guiding portion inserted into the joint body and engagement portions, the guiding portion guiding the tube so as to prevent the tube from vibrating in a radial direction of the joint body, the engagement portions elastically deformable relative to the guiding portion; and a restraining member mounted to the guiding member and restraining an elastic deformation of the engagement portions relative to the guiding portion.

1 . A piping joint comprising:
 a joint body being a hollow shape and formed with a passage;   a tube inserted into the joint body through the passage;   a retaining member mounted inside the joint body and located at a distance from an opening of the joint body, the retaining member supporting the tube inserted into the joint body;   a guiding member having a guiding portion and engagement portions, the guiding portion inserted into the joint body through the opening and arranged between an inner peripheral surface of the joint body and an outer peripheral surface of the tube, the guiding portion guiding the tube so as to prevent the tube from vibrating in a radial direction of the joint body, the engagement portions elastically deformable relative to the guiding portion and engageable with an outer peripheral surface of the joint member, wherein the guiding member is detached from the joint body when the engagement portions are elastically deformed with respect to the guiding portion; and   a restraining member mounted to the guiding member and restraining an elastic deformation of the engagement portions relative to the guiding portion.   
   
   
       2 . The piping joint according to Clam  1 , wherein the guiding member further includes a base, and the restraining member includes a restraining base and restraining engagement portions engageable with the base of the guiding member, wherein the restraining member is engaged with the guiding member via the restraining engagement portions engaged with the base of the guiding member. 
   
   
       3 . The piping joint according to  claim 1 , wherein the guiding member and the restraining member are arranged coaxially with each other. 
   
   
       4 . The piping joint according to  claim 2 , wherein the restraining engagement portions are elastically deflected relative to the restraining base so as to be engaged with the base of the guiding member. 
   
   
       5 . The piping joint according to  claim 2 , wherein the restraining base are integrally formed with the restraining engagement portions. 
   
   
       6 . The piping joint according to  claim 2 , wherein the restraining base is an annular shape.
